Thank you for these helpful how to videos that actually show how to get the job done. I am so tired of other sites that either just want to sell stuff or bs on a soapbox about the cars. Please keep them coming.

Good job, the number one rule when working on these cars. Take your time and do not rush.. If you stick by this rule, you can do most of the work yourself...

I appreciate how real your video is, I’m thinking of tackling the fuel injectors this winter and it’s nice to get advice on where the frustration points might be. I love Mercedes Source and Kent but he makes the jobs look so easy and clean, what seems like it should take an hour ends up taking four because things inevitably break, strip, get stuck or don’t fit.

Great Job! It’s always a chore to start when work was done on the upper fuel system. The warm start is mostly affected by the fuel accumulator next to the fuel pump. They were specifically integrated to eliminate warm-start problems. I got mine from Kent Bergsma Mercedessource. He has the best price for those. On your model the warmup regulator may also need to be checked. With greetings from Kansas, Peter

Man I appreciate your videos so very much! So much of the information from the MB manual assumes a level of mechanical knowledge that I don't have. It is really helpful seeing you figure out problems and then explaining them in a way I can understand. Now I am looking around for a good quality 5mm Allen socket so I can tackle my injectors!

Thanks just great I have a 107 350sl 1972 living in Denmark great video.

just so happens that I saw your other vid right after I made that comment. congrats on getting it done. makes it easier to enjoy the car when it behaves like it should.

I have a 1983 Mercedes SL380 and named her Erica she’s silver! I’m in Hawaii

Well done.

Great video

You have a fuel injector tester on the car, Just take the fuel dist loose leave all the lines hooked up, put the injectors back on the end of hard lines, jump fuel pup relay and press on the pintel to make the injectors spray, watch and evaluate. more than likely the fuel dist needs rebuilt, Just my 2 cents,, should have got a 560, they are so much a better car!

Wonderful

Hi. You mention problems with warm start...In k jetronic that is ussualy fixed by replacing the fuel accumulator.. Great job with the injectors.. washing them doesnt work.. they have a spring that wears out with time.

Funny enough, I just did the same thing on my SL380 (US) just two days ago. Couldn´t managed to exchange all of them due to the screws. But hey, I had some issues with the idle running (warm), too. If you need some support with it, let me know. The were several steps or areas I checked: There is an overvoltage relais on the passenger side (fuse was blown the whole time). Once this worked again, my idle running controller (not the Jetronic controller) quit its job, so it needed an overhaul. As well, two vacuum lines weren´t connected to the throttle valve properly. And I changed the o-rings on the fuel distributer and the diaphrame rubber (can cause too rich mix on one chamber). All necessary stuff, but in the end it was one fuel injector that cause an unstable warm idle run. And, there is the chance that somebody fiddled with the acceleration rods- if the one connected to the throttle valve was manipulated, it is slidely open in idle and causes a poor mixture. Checking the spark plugs can help to figure if this is air, fuel, vacuum or electronically related. Well anyways, I am just glad I stumpled across your vids. Feel free to hit me up to exchange about issues with those beauties. Thanks for your videos.

Luv it mate keep at it cobba

The carbon staining is no big deal, it's more about the spray pattern and flow rates..

Hey, try testing the warm up regulator. the name is a misnomer, as the WUR controls idle and starting t all temps.

im ready to replace me infjection, i have black smok , and need more them de injectors replace, thanks you for the start.

Have you try adjusting the sensor plate? Watch Pierre Hedary’s video on adjusting the height on the sensor plate.

Thinking about doing this job on my 82 380sl here soon. I was able to find the injectors on Amazon for $25 Where did you find those plugs? Do you have a link?

Invest in highest quality tools. If you don't 10 minute job will take you hours! When you replace fasteners always get the best stuff! No grade 2 or 5 on anything metric! 10.9 and 12 only! Are you sure these original screws were "socket heads"? they look like star heads to me (very common in automotive assembly). General rule is you cannot mix Allen wrenches with star bits. You will damage stuff.

Are you sure they were Allen screws to me they looked like Torx which Mercedes use a lot

Great video! Thanks for posting these. What is the part number for the rubber boots for the injectors?

What size are those replacement screws? About to tackle this job...

It looks like the screws holding down the injector plates are torque screws not Allen head bolts. That might be why you're having trouble getting them out.

Couple of questions...1) why did you decide to replace fuel injectors? (2) My car doesn't start in P most of the times. The person I purchased it from said that I should move the gear to N and try starting. I works every time. Not sure why and what the issue is, but cold or hot, 95% of the times my car starts only when the gear is in N. It just doesn't even crank in P. If you know why, let me know. I have the same exact car, including the color, 1982 model.

like you i destroyed a couple of the screws holding the clips in place. do you know the thread pattern and dimensions of the screw so i can look at homedepot for the replacement? thanks in advance.

100% fuel accumulator problem. Replace that with your fuel filter and you problem is solved.

Have you checked or changed the warm up regulator? It is a key element of the Bosch mechanical fuel injection system.

Change the fuel filter

Those look like torx and not allen
